Y = mx+b
1 = 2(1) + b
1=2+b
1-2=b
or
b=-1
equation
y = 2x - 1
answer:<span>a. y=2x-1</span>
Answer:
y =
x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 5 ← is in slope- intercept form
with slope m = 
Parallel lines have equal slopes, thus
y =
x + c ← is the partial equation
To find c substitute (- 6, - 5) into the partial equation
- 5 = - 8 + c ⇒ c = - 5 + 8 = 3
y =
x + 3 ← equation of parallel line
Answer:
She has 20 quarters.
Step-by-step explanation:
Alissa emptied her piggy bank for Disney world. She had $7.70.
If she had 10 pennies and twice as many times as quarters, then we can write the equation as
Q = 2P {Where, Q represents the number of quarters and P for pennies}
⇒ Q = 10 × 2
⇒ Q = 20
So, she has 20 quarters.
Therefore, she has 20 quarters. (Answer)
